When reissuing consolidated gift receipts from within Mail it will produce an incorrect receipt number if the field "Gifts.Receipt Number" is available in fields to include. The field doesn't need to be used in the document just included on the fields to include tab of the mail merge.

We are currently evaluating this issue and will update this article when we have more information.

Note this only affects consolidated receipts and not individual gift receipts

In the meantime:

Remove "Gifts.Receipt Number" from the available fields on the fields to include tab

Include "Gifts.Previous Receipt Number" on the fields to include tab and use this merge field in the merge document
